Valve Installation

WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
Personal injury or equipment damage caused by sudden release of pressure or bursting of pressure retaining parts might
result if service conditions exceed those for which the product was intended. To avoid injury or damage, provide a relief
valve for over pressure protection as required by government or accepted industry codes and good engineering practices.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
CAUTION
This valve is intended for a specific range of pressures, temperatures and other application specifications. Applying
different pressure and temperatures to the valve could result in parts damage, malfunction of the control valve or loss of
